We hardly use ours unless we're in a rough section and lugging the car. The thermostat is just another problem waiting to happen, and I wouldn't wire it to run straight off the ignition. Run it through a toggle switch.

Switched. After the motor is hott, we turn it on and leave it there for the entire race. Most of those fans draw about 6 amps so it's nice to be able to turn it off if you stall to get some extra juice for starting. That's why we did it that way.
not the samething that goes to the gauge. it would need to be a temperature switch that closes on a rise in temperature.instead of running the switch to a fan or other device you would run it to a light, or just have to co rider watch the temp gauge
